Yes, absolutely. The CPU is not the most expensive part in the phone. Every other part is sourced on the open market and Apple typically makes inferior choices compared to what's available.Exactly, it will be frustrating if they add 3GB in for 7 or 7s. Soon developers will create apps that need the 2GB, then you won't be able to use it on your 6. That is why Apple is lagging behind on the RAM. Not because they are cheap. Designing a new processor costs more than putting more RAM in. Do you guys SERIOUSLY think it is just Apple being cheap?
The proof is in their net margins (which take into account all the R&D) that are higher than all the other competitors.
